2 Claims. 1

This invention relates to portable refrigerators and has for its object to provide a compartment and mechanism arrangement lending itself to compact and economical construction adaptable to the incorporation of the compressing, freezing and condensing units in a cabinet of such size and balanced form that such a refrigerator may be of the table type, easily handled, and suitable for transient use as in small apartments.

Still further the said invention contemplates the provision of a cabinet having a central food chamber flanked by compressor and condenser chambers.

Still further objects and advantages subsidiary to or resulting from the construction and operation of the device will become apparent as the said invention is hereinafter further disclosed.

In carrying the said invention into effect, I may provide a generally circular central food chamber, housing a freezing unit, with a compressor chamber at one side thereof and a condenser chamber at the opposite side thereof, each of said chambers being provided with suitable means of access thereto, the upper and outer surfaces of the compressor and condenser chambers thereby offering unobstructed presentation to the atmosphere for the ready disseminating of heat from the mechanisms or structures therewithin. All of which is more particularly described and ascertained hereinafter, by way of example, having reference to the accompanying drawing, wherein;

Figure 1 is a perspective view of a refrigerator constructed to embody the present invention;

Figure 2 is a fragmentary phantom perspective view of the same showing the compressor unit;

Figure 3 is a vertical sectional elevation of the same; and

Figure 4 is a horizontal section of the same.

Similar characters of reference indicate similar parts in all figures of the drawing.

l indicates a central food cabinet, preferably of a generally round or elliptical form in horizontal cross section and of double Walled construction to accommodate any suitable insulation 8; H being a door providing access to the interior of the said food chamber. Flanking the said food chamber are chambers l2 and I3 provided with doors l4 and I or other suitable means of access thereto and the said chamber l2 houses a compressor unit including the motor 2 coupled to the compressor 3 by the belt drive 4. The chamber l3 houses the condenser unit 9.

Within the upper part of the food chamber is a freezing compartment 6 shown as housing ice cube trays and encircled by the freezing coil 5 which coil has the usual conduit connections with the compressor unit and the condenser unit.

It is a. bail or handle on the top of the food compartment about which the weight of the unit is substantially balanced in order that the device may be easily carried by means of the said handle from one place to another. It is intended that any suitable means of plugging the motor circuit into convenient wall sockets may be provided so that the device is readily portable and calls for no special installation.

The compressor and the condenser chambers are exposed to the atmosphere on all sides except where they laterally abut the food chamber and a high degree of heat dispersal therefrom is easily insured. Furthermore the arrangement described admits of a relatively large shelf surface within the food chamber relative to the height of the device due to the flanked arrangement of the compressor and condenser chambers with consequent economy of usable space.

This invention may be developed within the scope of the following claims without departing from the essential features of the said invention, and it is desired that the specification and drawing be read as being merely illustrative of a practical embodiment of the said invention and not in a strictly limiting sense.

What I claim is:

1. In a device of the type described, walls defining a generally circular food chamber, a compressor chamber at one side thereof, and a condenser chamber at the opposite side thereof, all of said chambers being provided with means of access thereto, a freezer unit in said food chamher, a compressor unit in said compressor chamber connected to said freezer unit, a condenser unit in said condenser chamber connected to said freezer unit, and to said compressor unit and a carrying handle on the top of said food chamber intermediate the compressor and condenser chambers.

2. In a device of the type described, walls defining a generally circular food chamber, a com- 'pressor chamber at one side thereof, and a. condenser chamber at the opposite side thereof, all of said chambers being exposed on front, back and top to the atmosphere and provided with means of access thereto, a freezer unit in said food chamber, a compressor unit in said compressor chamber connected to said freezer unit, a condenser unit in said condenser chamber connected to said freezer unit and to said compressor unit, and a carrying handle on the top of said 10 Number 4 food chamber intermediate the compressor and condenser chambers.
